Nowadays more and more people think that it is very important to spend much money on space development. Is it a good idea to neglect problems on Earth? On the one hand, it is really important to foster development of the space industry. Furthermore, it is a good opportunity to gain new knowledge. It would be useful to know about space, rather than just be a victim of it. At the same time our planet has limited resources and space exploration is a necessity to mankind. Staying on Earth will lead to extinction. Some of the reasons are: lack of natural resources, comets, nuclear war and world-wide epidemic.On the other head, there are so many reasons to spend money in the first place on the needs of our population. Besides that, space exploration has had a lot of waste and lacks purpose. Many people believe that the development of space can lead to global catastrophe or bring disaster upon humanity. Recently there have been calls to reduce programmes in space. I think it would be a serious mistake. To sum up, I should say that science unites people and different countries cooperate successfully today for the benefit of people.
